Template for positioning multiple seats in a row

Abstract

A planar, T-shaped template member has a linear leg section with a first end thereof intersecting a cross bar section at a center thereof. The cross bar section has opposed ends, each end having a feature at a selected location therein. The cross bar section also has a circular aperture there through positioned opposite the leg section, with the circular aperture connected to an access channel extending to an edge of the cross bar section opposite the linear leg section. The linear leg section has a protrusion at a second end thereof opposite the cross bar section. The protrusion is sized to pivotally fit into the circular aperture and access channel of an identical T-shaped planar template member, thereby allowing pivotal movement between connected planar T-shaped template members. A large number of such templates can be connected together in a line.

Construction

(8) The invention is a template that provides location of the fastening points on a support surface for multiple seating units in a row. A plurality of such templates can be linked together so that multiple fastening points for a row of seating units can be determined at one time. In addition, the plurality of linked templates can be adjusted to provide a straight line of seating or a curved line of seating. Careful placement of the anchoring fasteners into the support surface is required to produce proper alignment of rows of adjacent seating units. Often, it is necessary to provide curvature of the rows of seating units for aesthetic or utilitarian purposes. This adds to the necessity for precise placement of the anchoring fasteners. Errors in location of one of the holes for the permanent fasteners can cause misalignment for the whole row of seats. Such errors are costly to repair at best.

(9) Referring now to FIG. 1, the device comprises a planar, T-shaped template member 10 having a linear leg section 20 with a first end 22 and a second end 24. The first end 22 thereof intersects a linear cross bar section 30 at a center thereof. The cross bar section 30 has opposed ends 32, 34 each end having a feature 36 at a selected location therein, the feature 36 providing location for fasteners on the support surface. The feature 36 may be an arc indentation, as shown in the Figures, or an aperture. The cross bar section 30 also has a circular aperture 40 there through positioned opposite and aligned with the connected leg section 20. The circular aperture 40 is connected to an access channel 45, which provides an opening at an edge of the cross bar section 30 opposite the linear leg section 20. The linear leg section 20 has a protrusion 50 at a second end 24 thereof opposite the cross bar section 30. The protrusion 50 is sized to pivotally fit into the circular aperture 40 and access channel 45 of an identical T-shaped planar template member 10, as shown in FIG. 2, thereby allowing some degree of pivotal movement between connected planar T-shaped template members 10. The protrusion 50 is preferably also circular in shape and fits into circular aperture 40 and access channel 45. Alternatively, the protrusion 50 is a polygon, such as a square or hexagon, either of which fits into the circular aperture 40.

(10) Referring now to FIG. 3, which illustrates a further embodiment of the invention, the surface of the cross bar section 30 surrounding the circular aperture 40 contains a plurality of spaced apart surface lines 60, with each line 60 extending radially outward from the circular aperture 40. In addition, the surface of the protrusion 50 of the second end 24 of the linear leg section 20, sized to pivotally fit into the circular aperture 40, contains a like plurality of spaced apart surface lines 60 each line 60 extending radially inward from the edge thereof. The spacings between the radially extending lines 60 of the protrusion 50 and those of the cross bar section 30 are not identical. Thus, alignment of a selected pair of surface lines 60, one from each surface, results in a corresponding angle between adjacent, connected planar template members 10. As shown in FIG. 3, the lines denoted as 25 of cross bar section 30 are aligned with the lines denoted as 25 of each protrusion 50. Thus, the angles between adjacent connected template members 10 in a string are identical. This constant angle between adjacent template members 10 is clearly shown in FIG. 4. Thus, identical angles between adjacent, connected planar template members 10 can be maintained across a long string of such template members 10, which produces a smooth curve from the first to the last template member 10. Alternatively, alignment of the lines denoted as 0 of cross bar section 30 with the lines denoted as 0 of each protrusion 50 produces a straight line from the first to the last template members 10.

(11) Referring again to FIG. 4, a cross bar end piece 70 can be used to anchor each end of a string of connected planar template members 10, as illustrated in FIG. 4. The linear cross bar end piece 70 has a first end 72 and a second end 74 with an arc indentation feature 76 at each end thereof. The end piece 70 has a circular aperture 40 connected to an access channel 45, which provides an opening at an edge of the end piece 70. Protrusion 50 of the template member 10 fits into the circular aperture 40, as shown at the right end of the string of connected planar template members 10. The end piece 70 includes radial lines 60, as described previously, used to rotatably position the end piece 70 relative to the string of connected template members 10. The T-shaped template member 10 at the left end of the string of connected template members 10 in FIG. 4 includes the above described rotatable connection between the leg section 20 and the linear end piece 70 to properly orient the arc indentation features 36 at each end of the linear end piece 70.

(12) To properly position parallel strings of connected template members 10, long spacer connecting pieces 80 between adjacent strings of connected planar template members 10 assist in maintaining constant spacing between the adjacent strings of connected template members 10, as illustrated in FIG. 5.

(13) The planar, template member 10 and is preferably fabricated from a rigid material, such as fiber board or polymeric resin plastic, as are the spacer connecting pieces. Thus, the planar, template members 10 and the cross bar end pieces 70 can be used multiple times, reducing the per use cost for each of the templates 10 and 70.

(14) While the invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
